My invention .relates to railway rolling stock and consists in all of the novel features described herein and illustrated in the accompanying drawings and particularly in the manner of mounting a third or fourth point guard, guide, or supporting member of the spring plank in relation to the brake beam, which is hung directly from the truck transom or frame, it has been necessary to make the supporting member very broad,or to broaden the shoe or other engaging elementon thebeam, or to provide broad plates on the supporting member to prevent the brake beam from working off of the supporting member. 7

The main object ofthe present invention is to avoid the necessity of such provision V and I attain this object by mounting the supporting member on a trucktransom whereby relative movement transversely of thetruck between the brake beam and thesupporting 0 member is eliminated. v

" Another object of my invention is to avoid the attachment of brackets to the spring plank for mounting the'sup'porting member.

Another object of my invention is to facilitatethe application and removal of the supporting member to and from the remainder of the truck structure. Another object ofmy invention is to provide the support mounting bracket as an integral part of the truck structure and thereby eliminate the necessity of supplying a separate bracket and elements for securing it to the truck.

These and other detailobjects of my in-' vention are attained in the structure illustrated in the accompanying illustrations in which f v Figure 1 is a vertical transverse section through-a car truck andis taken substantially on the line 1-3-1 of Figure 2. i

Figure 2 isa top view of the structure l shown in Figure 1. V Figure 3' is a vertical longitudinal sec tion taken on the line 3-3 of Figure 2.

Figure 1 is a corresponding section of fa detail of a modified form of my invention; Figure 5 is a similar section illustrating anothermodification.

The truck indicated is of theiusual fourwheel type includingwhcels 1, axles 2, with Journals 3 which support the truck side frames a through theusual journal boxes (not shown). Transoms 5 are are shown as united at their ends by the member 6' and mounted as a unit in the'side frames 4, but these transoms may be formed integrally with the side frames if desired.v Swing links 7 are suspended from the transoms pins 8 and carry-across bar 9 which supports the channel spring plank 10 mounting the elliptic spring 11 which carries the truck bolster 12. This arrangement provides for lateral movement of the truck bolster to relieve the side thrust on the frame journal boxes, jour p,

nals, and wheel flanges arising from curvatures in the trackor unevenness in therails.

Thebrake beam indicated is of the usual truss type comprising a compression member 13, a tension member 14, and astrut 15. The

beam mounts; the usual brake head 16 at'each end and the head and beam are suspended from brackets 17, formed on transoms-5, by

shaped transom 5 is a bracket, including sides or legs 19 and seat elements 20 connecting legs 19 and preferably having between them a depression 21. The upper edge of element 20 is spaced from the upper end of the bracket and preferably flangedas indicated at 22 to provide a supporting ledge. The bracket issubstantially aninverted U shaped structruck for mounting a third point support. g p U structure may be made w thout departing a I have shown I fourth-point supports, but, it willbe underfit into the depression 21 in the bracket.

Thepin 26 engages the offset and'holds; it nested inthe depression; 21, the pin being.

seated in openingsprovidedin thesides 19 of the bracket. f'

Preferably, but not necessarily, member- '23 is of spring-material and is somewhat dis 'torted when assembled, as shownin Figure 3, to prevent rattling in sitsmounting, and also. provides elastic support fo1;tl1e brake beam. f

the brackets arranged, for

stood that the transom could be provided with a single bracket at the center of'the Figure 4: illustrates a "modified structure in'which the inverted U shapedbra'cket 27- is formed separately from the transom29 and secured thereto by rivets 28 through its bar, 30; Otherwise, the structure illustrated mired is the same. as thatrshown n Fi Figure 3..

In the modification illustrated in Figure 2 5, two elements 31, and 32 are seated, between theibracket web 33and the pin l p Element 32 corresponds to the el.eme'nt;23 previously described and element 1 3L constitutes a sec; ond guard or support memberofg-heavier section with its lower portion extendingv under the compression. member 3510i: the beam and normally spaced b'elowf element 32. Eleg merit 31 may be rigid or of "spring material;

although spring materialisq desired. Y Ele:

My invention is notilimited'initsapplicaf tion to the centertransoins of the truck, but may be applied to the end transoms or end rails of the truck frame and maybe used with.

clasp brakes} I s V V Figure Gillustrates such an application of, my inventiomincluding a b'rakebefam guard, guide, (ii-Support memberS'Z having both of its end portions turned up similar to the sup: ported end of the other forms of my inven-1 39. The truck end railaflconnecting the wheel pieces 43 s shown, is provided with a depending bracket 42 corresponding to the bracket 39 on the bolster transom.

The member 37 may be of ri id or spring secured at one end to thespring plank 41-3 in the usual manner the spring plank being carried fromth'e truck frame by the swinging In Figure-7, I illustrate another arrangementof aguard, guide, orsupport member for clasp brakes in which the truck end members 45 do not extendclear across t-hetruckframe but project. inwardly far enough to provide a. depending bracket 7&6 similar to bracket 42 shown in Figure 6. Separate support members 47 are mounted on eacliof the I brackets A6 and each of the corresponding brackets 48, which will depend from, the bolster transom 4 9,. 'Thisstructur e is very similarto that shown in Figure 6, but substi tutes separate support members 47. for the r continuous'support member 37.
